Kinematics Analysis Of The Technique Of Make An Effort Finally For Women Discus Of The 11th IAAF World Junior Championships

In the field events project, the discus throw is one take the strength as the foundation, take the speed as the core and along the multiple spindle revolving throwing events. Simultaneously it is also the Olympic Games, the continent transports the meeting, the international championship and the national games and so on the significant comprehensive games competition must one of essential athletics projects. In more than 100 year developing processes, it experienced the multiple technology to transform, from-situ threw to lateral on step throws develops revolving to throw the technology finally, was disliking revolving to throw the technical aspect to present the wave form, the take-off type and movements and so on back cake type. We are not difficult from discus's technology successional variation process to see the discus technology are an item quite complex throw the technology. At the same time, looks over these technologies to transform, is by increases instrument's work distance, enhances the instrument to get rid the speed is the goal finally. Because of according to the instrument flight's range formula S=V2sin2α/g, may know instrument's flight initial velocity is affects the discus throw result the most primary factor. before "the revolving approach" is makes an effort, to accumulate the momentum finally the process, is the entire technical link's important component. The speed strength is obtains the getting rid of initial velocity key, the training core is a speed without doubt most greatly. "the human body instrument system" to throws the direction regarding the ordinate axis the revolving approach, is distinguishes between other straight line approach's field events project characteristic. Looking from the entire discus throw process, the discus throw running rate is the process which increases unceasingly. Thus it can be seen, the modern discus throw technology's development, mainly take raises the getting rid of speed as a core, seeks for various links speed structure and the movement structure optimal fit and the whole combined earnings, then the enhancement gets rid the benefit. We study the discus technology the goal are, carries on the overall analysis to various links' speed structure and the movement structure, attempts to seek for the top athlete each technology characteristic, under namely each link's speed rhythm and the movement various structures' optimum matching, will conduct a step deep research for us to build the foundation from now on.This research take the 11th world youth championship female discus first six athletes as the object of study, uses the video recording analysis and the mathematical statistic method, makes an effort to them the technology to carry on the kinematic analysis finally, discovers technical the superiority and the insufficiency, with the aim of permeating the understanding to master the contemporary world youth woman discus technology the development characteristic, enables our country's female discus athletes to obtain certain model, urges its movement technology to achieve the optimization, further raises our country female discus movement level. The result indicated:1, is making an effort the stage to stress that finally large scale whips the effort to enhance the discus in turn from bottom to top to get rid speed control being suitable to get rid the angle.2, makes an effort the technology should finally to have the reasonable speed rhythm, by prominent technical movement personalization.3, makes an effort finally accelerating ability has certain influence to discus's final result.4, the athlete will make an effort the stage body's center of gravity to have the high and low fluctuation finally, but will fluctuate the scope will not be big, to the movement result's will influence not be very big.5the.finally makes an effort the stage two foot's positions and is away from to the technology completes smoothly has certain influence.6, makes an effort the stage athlete to grasp accurately finally sends the strength opportunity, has the very vital significance to the movement result.
